However, the double eyelid formed by embedding thread has little trauma to the tissue, and only at those points where the suture passes, less fibrous tissue is formed, and the artificial adhesion is also small. If the drooping force is large, the adhesion is easy to loosen. So theoretically, most of them can last for 3-5 years, but some of them can last longer or even exist forever.
In order to increase the durability of double eyelids, 4-5 stitches can be sewn when suture and ligation are performed. And bring the tarsal plate, so that the skin and levator palpebrae superioris can be more firmly attached to the tarsal plate, and the double eyelids will naturally last longer.
